QLS Laminated Sand Filter is an efficient and reliable filtration product. Made of high quality polyester and fiberglass materials with anti-corrosion coating for added durability.Using a new vacuum process, the surface of the filter body becomes brighter and smoother.The new appearance design increases the height of the filter layer, resulting in better filtration effect. And the tank body is smooth, rich in color and high brightness. In addition, It is equipped with a multiport valve and a clean water observation mirror for easy monitoring and filtration, and is easy to maintain and clean.
Smooth filter body surface finish via a new vacuuming process.
New appearance design makes the filter layer higher, thereby improving the filtering effect.
Glass fiber tank is made of corrosion-resistant gel coat.
Tank body is smooth, colorful and high-brightness.
Equipped with a multiport valve.
With a clear water inspection mirror for monitoring the water filtration.
Easy to maintain and clean.
1. Swimming pool
As the core filtering equipment, it is used in conjunction with the sand filter to remove suspended solids and impurities in the water and keep the water clear. Some high-end swimming pools use laminated filter linked with ultraviolet or ozone disinfection systems to improve water quality and safety.
2. Water parks
Facing the water quality challenges brought by high flow of people, laminated filters undertake the main water purification task with their large flow processing capabilities and stable performance, and are suitable for wave pools, lazy rivers and other areas.
3. Aquariums and oceanariums
Used in life-support systems to filter organic matter and particulate matter in aquaculture water bodies to ensure the health of aquatic organisms. It is often used in combination with other filtration technologies (such as protein skimmers).
4. Waterscape projects
Such as landscape lakes, fountains, etc., laminated filters can effectively control the turbidity of water bodies, prevent algae growth, and maintain visual beauty and ecological balance.
5.Water treatment engineering
In fields such as artificial lakes, aquaculture, and industrial wastewater pretreatment, laminated filters serve as pre- or main filtration units and have good chemical stability and can adapt to complex water quality environments.
